If you press "Add to Cart" the second it releases on an online retailer, does it automatically belong to you if it goes in the cart? Or, do you have to check-out faster than someone else who may also have it in the cart?

I've never had to do this trigger-finger purchasing until now that I'm interested in Air Jordan's, lol.

I've only done it twice and I wasn't exactly sure of the science/technology behind it. Both times, I clicked the minute the countdown expired and was placed in a "line", where I had to wait several minutes for my request to be processed (a website window explained as such). It worked each time, but I imagine it does not work for everyone.
